Specifioation of Letters Eatentl 4 Patented Mar. 6, 191?.

Application filed April 6, 1916. Serial No. 89,327.

To all whom it may concern:

Be it known that I, ALVIN V. ROWE, a citizen of the United States, and a resident of G-alesburg, in the county of Knox and State of Illinois, have invented a new and useful Anchor, of which the following is a specification.

invention relates to that type of anchors which are adapted to be embedded in concrete and which are adapted to receive, engage or retain bolts, clips, supports, or other co-acting elements.

One of the objects of the invention is to provide an anchor which is so constructed that it will withstand the maximum of draft that the metal will bear without even the slightest movement of the anchor in its bed.

Another object consists in so forming and arrangingthe structural features of the anchor that a bolt or other co-acting element may with facility and case be engaged therewith and rigidly held thereby.

Minor ob ects will presently appear.

in the accompanying drawings:

Figure 1 is a perspective view of an an chor embodying my improvements;

Fig. 2, a sectional view of the anchor as it appears in use, the plane of the section being taken substantially in the line 2.2 in Fig. 1, but with the bolts shown in full lines.

Fig. 3, a perspective of an anchor embodying; most of the structural features of the .one shown in Fig. 1, the tongueshow- 7 ever being omittedf Considering the drawings in detail and Fig. 1 in particular, 2 indicates a strip of metal bent or otherwise formed to comprise a median depressed portion 3 preferably having openings l, the adjacent portions being then bent upwardly as shown by .5, thence horizontally and outwardly as shown by 6 and thence downward to form legs 7. 8, 8 indicate relatively large openings in the vertically arranged portions 5, and 9, 9 indicate smaller openings in the floor members (3, communicating with the openings 8. A suitable-number of slits are made in each leg, whereby to provide openings 10 and tongues 11, the latter formedby bending outwardly thefree edge of the piece formed by the slitting operation.

14c, 14 indicate bolts each of which has a square shank 15 which snugly fits the adjacent slot 9, its headl'? being of a size greater thereof, the soft material flowing or creeping through the openings 9 and 10 and lodging on the now embedded portion 3 and said tongues. ()r the soft concrete may be poured over th e anchor after it has been positioned.

In either case it is preferred that the top of the concrete lie flush with the top 6.

The preferred placement of the bolts 11 i is shown in Fig. 3, wherein the shank 15 is resting squarely in the channel 9 and the head 17 restin on the concrete and restrained from both upward. or inclining movements by the top 6. If it be desired, the concrete may be scooped out adjacent the openings 8 and 9, whereby to provide a pocket in which the bolt head may seat and from which it may be removed at any time,

but I have found these pockets objectionable in that they collect hairs, dust and. other unsanitary matter. I

One of the chief advantages of the inveii tion is that the depressed horizontalmein her 3 is embedded deeply in the concrete,

The strain or stress of the parts to which the bolts are connected will cause the strain of the bolt-heads to be on the floor-sections 6. The double set of vvertically arranged re sistance members 5, and eiiectually resist openings 8 and 10 and it will be evident that in order to cause either of the perpendicular members 5 or 7 to be displaced the upward draft on the anchor would have to be sufiicient to cause the cross bars (which afford the lower edges of said openings) to cut through the concretea manifestly impossible thing.

The invention shown is primarily in ended aniancher for posts, plates, oists which the t and is especially adapted for use in connection with the vertically arranged stallposts of the modern cattle-barn equipment.

Having thus described the nature, purposes and operation, and having set forth a few of the numerous advantages of my invention, I claim as new and desire to secure. by Letters Patent the following, towit:

1. A metallic anchor having a centrally arranged horizontal portion adapted to be embedded in concrete and having oppositely arranged floor-level portions connected thereto by perpendicular portions, the latter portions provided each with a relatively wide opening and the floor-level portions )rovided each with a relatively narrow slotiikc opening communicating therewith.

2. The combination with a fresh concrete bed, of an anchor comprising a pair of relatively outer horizontally arranged top portions and a centrally arranged horizontal portion having an opening through which the soft concrete is adapted to pass, and having legs each of which is provided with a transversely arranged opening into concrete is adapted to flow, the

" upper portion of the anchor provided in jacent floor-level each side with an opening formed partly in one of the said top portions and partly in a vertical portion adjacent it.

8. The combination with a concrete bed, of an anchor having a substantially U- shaped central portion embedded in the concrete, the terminals of said portion bent thence horizontally to constitute floor-level portions the ends of which are bent downward and embedded in the concrete, the limbsof the U-shaped portion and the adportions provided each .with an aperture portions of both, said apertures adapted each for the passage of the stem and head of a bolt, and each floor-level portion restraining its coacting bolt.

4. An anchor formed of a singie strlp of metal and comprising elongated parallel legs each of which is provided with a transverse aperture. the metal at the upper end of each leg directed horizontally inwardly and the middle portion bent to form a depending U, the angle at each of said inwardly directed portions and the .U being cut away to permit the lateral sliding of a bolt-head through the vertical part thereof, the horizontal cutaway portion being narrower-than the vertical cutaway portion.

5 An anchor formed of a single strip of metal and comprising elongated parallel legs. the metal at the upper end of each leg directed horizontally inwardly and the mid: dle portion bent to form a depending U, the angle at each of said inwardly directed portions and the -U being cut away to permit the lateral sliding of a bolt-head through the vertical part thereof, the horizontal cut- :t'ornled by cutting away i like elements, of

away portion la ng narrower than the vertical cutaway portion.

(3. The combination with bolts, of an anchor formed of a single strip of meta. and comprising elongated parallel legs, the metal at the upper end of each leg directed horizontally inwardly and the middle por tion bent to form a depending U, the angle at each of said inwardly directed portions and the U being cut away to permit the lateral but not the vertical sliding of one of said bolt heads therethrough.

7. An anchor formed of av single strip or metal and comprising parallel legs, the metal at the upper end of each leg directed horizontally inwardly and the middle portion bent to form a depending U, the angle a each of said inwardly directed portions and the U being cut away to permit the lateral sliding of a bolt-head through the vertical part thereof, the horizontal cutaway portion being narrower than the vertical cutaway portion.-

8. An anchor termed of a single stri of metal and comprising parallel legs, eac of which is provided with an aperture, th metal at the upper end of each leg directed horizontally inwardly andv the middle portion bent to form :1 depending U, the angle at each of said inwardly directed portions and the U being cut away to permit the lateral sliding of a bolt-head through the vertical )art thereof, the horizontal cutaway portion eing narrower than the vertical cutaway portion.

9. The combination with inverted boltlike elements. of an anchor formed of a strip of metal and comprising parallel. legs, the metal at the upper end of each leg dlrected horizontally inwardly andthe middle portion bent. to form a depending U, the angle at each of said inwardly directed portions "nd the U being cut away to permit the .ateral sliding of the hea 0 f one of said bolt-like elements therethrough, and the horizontal cut-away portion being narrower than the head but wider than the shank of said bolt-like element 10. The combination with inverted boltlike elements, of an anchor formed of a strip of metal and comprising parallel legs, each of which is provided with a transverse aperture, the metal at the upper end of each leg, directed horizontally inwardly and the middle portion bent to form a depending U,

the angle at each of said inwardly directed portions'and the U being cut away to permit the lateral sliding of the head of one of said bolt-like elements thercthrough, and the horizontal cutaway portion being narrower than the head but wider than the shank of said Holt-like element.

11. The combination with inverted boltan anchor formed of a strip of metal and comprising parallel legs, each of which is provided with atransverse aperture, the metal at the upper end of each leg directed horizontally inwardly and the middle portion bent to form a depending U, the 5 angle at each of Said inwardly directed portions and the U being cut away to permit the lateral sliding of the head of one of said bolt-like elements therethrough, and the horizontal cutaway portion being narrower than the head but Wider than the shank of said bolt-like element, the anchor being provided with an opening into which cement I I at Galesburg, Illinois, this 3d day of April,
